Lab Report Morphological Unknown Lab Report
Introduction: There are many types of
microorganisms in the world that may seem alike
but are very different in function and purpose.
That is why when one has to find what an unknown
organism is he or she sees that its difficult to
classify it based on its outer appearance. That is
why there are many ways in order to classify
microorganisms under microscopes. Two of the ways
to identify microorganisms are by looking at the
colony and cell morphologies or by conducting a
series of stain procedures on the microorganisms.
A colony is a mass of microbial cells (Colome,
Ex6:28). Morphology is the colonys structure and
form. There are six parameters used to describe a
colonys morphology: overall appearance, colony
margin (edge), elevation, size, pigmentation, and
consistency (Colome, Ex6:28).

Although colony
morphology isnt the best way to identify
microorganisms, its helpful in recognizing some
types. The other more efficient way to identify
microorganisms is by staining them. A stain is
used to color a microorganism and its background.
On September 25, 2000, each microbiology lab
student was given an unknown microorganism and was
told to use series of staining procedures to
identify his/her unknown organism. The
identification key on page 61b of the microbiology
lab manual was used in identifying the unknown
organisms. Science.
